Abstract

See full text

The device and method are for one shot greasing of tractor trailer fifth wheels and other structures. The device has an upper tube and a lower tube where the upper tube acts as a piston to push down on the lower tube to dispense a grease supply. The lower tube bottom, or a bottom cap connected thereto, has a plurality of dispensing orifices. Preferred embodiments include a stop mechanism to prevent relative movement of the upper tube and lower tube prior to dispensing, and a removable seal on the bottom that prevents grease release until the seal is removed.
